Mmm I love Jam Tots BerryPlushes too. I'd have all them if my wallet agreed to it.

The others have given great brand suggestions, the only things I can add are about your concerns - regarding the legs being pushed too wide, don't forget that we all grew up in flats, and while flannelettes are pretty trim, terry flats are pretty full on, and they didn't seem to do any harm! Also, with squashing his bits, maybe see what your partner thinks - I know, for example, that I used to wipe so gently while DH would just sort of whack about during changes and the little guys didn't seem to mind! You could also try going up a size with the Ittis? I know mine were in Mediums pretty early on, the first because he was so tall, and the second cos he was so chubby!
